ABSTRACT:
A liquid phase sintered dense composite body comprising a hard refractory metal carbide which is densely cemented by sintering with a metal or alloy components. The sintered composite body incorporates at a surface or in the interior a multiplicity of metallic elements consisting of coarse grains, strands and/or plates of either the same metal or alloy as the cementing component or metallic elements having a melting point at least 120.degree. C. higher than the temperature at which the liquid phase takes place on sintering. This liquid phase sintered dense composite body is manufactured by placing the coarse grains, strands and/or plates on the surface or within the compacted powder mixture prior to the liquid phase sintering operation.
